1、What is solnan (1) Introduction Solana is a powerful open source project that implements a new, license-free, high-speed layer-1 blockchain. Created in 2017 by former Qualcomm executive Anatoly Yakovenko, Solana aims to scale throughput beyond what popular blockchains typically achieve while keeping costs low.Solana implements an innovative hybrid consensus model that combines a unique proof-of-history (PoH) algorithm with a lightning-fast synchronization engine (aka another version of proof-of-stake, PoS). As a result, the Solana network can theoretically process over 710,000 transactions per second (TPS) without the need for any scaling solution. Solana's third-generation blockchain architecture is designed to facilitate the creation of smart contracts and decentralised applications (DApps). It supports a range of decentralised financial (DeFi) platforms as well as a non-homogenised token (NFT) marketplace. The Solana blockchain was launched during the blockchain boom of 2017. The project's internal test network was released in 2018, followed by multiple test network phases, culminating in the official launch of the main network in 2020. (2) How does Solana work? The core component of the Solana protocol is proof-of-history, a computational sequence that provides a digital record to confirm transactions that occurred at any point in time on the network. It can be represented as a cryptographic clock, providing a timestamp for each transaction on the network, and a data structure that can be simply added to. PoH relies on PoS using the Base Byzantine Fault Tolerance (BFT) algorithm, an optimised version of the Practical Byzantine Fault Tolerance (pBFT) protocol, which Solana uses to implement consensus. Tower BFT keeps the network running securely and additionally acts as a tool for verifying transactions. In addition, PoH can be thought of as a high frequency verifiable latency function, a triple function (setup, evaluation, verification) that produces a unique and reliable output. vdf maintains order in the network by proving that block producers have waited long enough for the network to move forward. Solana uses the 256-bit Secure Hash Algorithm (SHA-256), a set of proprietary cryptographic functions that output 256-bit values. The network periodically samples the numbers and SHA-256 hashes, providing real-time data based on the set of hash values contained in the central processing unit. The Solana verifier can use this hash sequence to record specific data created prior to the generation of a specific hash index. The timestamp of the transaction is created after this particular block of data is inserted. In order to achieve the claimed large number of TPS and block creation times, all nodes on the network must have cryptographic clocks to track events rather than waiting for other validators to verify transactions. (3) What is SOL SOL is a native token on the Solana chain that uses the delegated PoS consensus algorithm, where miners delegate SOL to validating nodes to participate in maintaining the network and receive rewards. SOL has three main use cases: pledge, transaction fees and governance. The SOL token mechanism sets SOL to have an initial inflation rate of 15%, after which the previous 15% is reduced each year and remains constant after reaching a long-term stability rate (1-2%). This token mechanism allows for rapid growth in SOL supply in the early years and stabilisation of SOL supply in the later years. With regard to the total number of Solana tokens, there will be over 500 million tokens in circulation and the total supply of Solana is currently over 511 million tokens - Solana's circulating supply is just over half of this figure. Approximately 60% of SOL tokens are controlled by Solana's founders and the Solana Foundation, with only 38% set aside for the community. SOL can be purchased on most exchanges. Solana's top cryptocurrency exchanges include Binance, Coinbase, KuCoin, Huobi, FTX and others. (4) Advantages ①Low fees The transaction fees for Ether have affected the normal use of DeFi by users. Currently, assuming ETH is 2000 USDT, a transaction providing liquidity through Uniswap V3 costs around $40 when Gas is 30 Gwei. The cost to Solana to complete a transaction is 0.000005 SOL, which is about 0.017 cents. This cost can be ignored for most DeFi transactions. ② Scalability Scalability can be achieved by reducing transaction fees and increasing the speed of transaction confirmation. For an underlying public chain, this means being able to support more applications. Then for a project to choose a public chain, their main concern should be the development and maintenance cost and user experience. Therefore, the 50,000 TPS designed for the Solana public chain provides it with strong scalability, enough to attract new projects to deploy it, plus the wormhole protocol enables interoperability with Ether, greatly reducing the risky cost of migrating projects on Ether to Solana. (5) Disadvantages (1) While the Solana blockchain can compete with high-end blockchain projects, it is still vulnerable to centralisation as it does not have many blockchain validators. Anyone on the network can become a Solana verifier, but doing so is still difficult because of the large amount of computing resources required. ②The Solana protocol still marks itself as a beta version of the main network; in other words, it does not deny that there may be bugs and errors.

1. The content introduced above is only about the basics of cryptocurrency, which is related to whether we can make money through cryptocurrency. Cryptocurrencies make money not only by scientific methods to increase income, but also by finding ways to save money. The handling fees are small, but they must not be ignored. I have calculated that with frequent transactions and long trading hours, the accumulation of fees can add up to more than 10,000 U a year. Next I will introduce a few common ways to reduce fees on large trading platforms. (1) Lowering Binance's fees Binance is currently the world's largest digital currency exchange, and you must sign up for Binance if you want to speculate on coins. The transaction fee is deducted from the assets received. For example, if you buy Ethereum/USDT, the fee is paid in Ethereum. If you sell Ethereum/USDT, the commission is paid in USDT. Example. You place an order for 10Ethereum at a price of USD3,452.55 per share. Transaction fee = 10Ethereum0.1% = 0.01Ethereum Or you place an order to sell 10Ethereum at 3,452.55 USDT per share. Transaction fee = (10Ethereum3,452.55USDT)*0.1% = 34.5255USDT What many people do not know is that the Binance transaction fee can also be reduced. If you want to reduce your Binance trading fees, you must register using the invitation link below or use the invitation code "Q022W7SC". https://accounts.binance.com/en/register?ref=Q022W7SC

(2) Reducing OKX fees OKX is a professional digital currency trading platform loved by many users, and its transaction fees can be reduced. Depending on the volume of transactions, OKX divides its users into two levels: normal and professional. Ordinary users are graded according to their OKB positions, while professional users are graded according to their trading volume and asset size. The different tiers determine the trading fees for the next trading day. When calculating the fee levels, if the coin trading volume, total trading volume of delivery and perpetual contracts (USDT delivery contract, coin-based delivery contract, USDT perpetual contract, coin-based perpetual contract), option contract trading volume, and asset volume meet the conditions of different fee levels, users will enjoy the fee discount of the highest level. First method: OKX has an official maximum saving of 20%. Use the link below to register with OKX and save 20% on fees. https://www.ouyi.business/join/BTC1ETH Second method: Open the OKX website and enter "BTC1ETH" in the "Invitation Code" on the registration page to see the cashback percentage: 20% at the bottom. Be sure to enter this invitation code, otherwise you can not get 20% cashback percentage. (3) Reduce FTX fees FTX is currently a very fast-growing, contract players more exchange, you must register FTX if you play the contract. if you want to reduce the FTX transaction fees, you must use the following invitation link to register. https://ftx.com/referrals#a=121031692 3, trading road is long, together with forward Want to know more about how to reduce the commission? telegram: btcethcool We have set up a community dedicated to researching trading, add telegram friends to pull you into the community.
